Definition
Extraction in which a sample dispersed in water and a water immiscible organic solvent (extraction phase) in separate flasks are heated simultaneously and their vapours co-condensed and separated into two streams in which water is returned to the sample flask and the extraction phase to the organic solvent flask.Apparatus for simultaneous steam distillation-solvent extraction with a lighter-than-water extraction phase. A = aqueous sample solution or slurry; B = immiscible organic solvent and receiving flask for extracted compounds; C = bowl for phase separation; D, E, F, and G are solvent or vapour transfer arms; and H = entry port for additional solvent or alternative sample introduction position for continuous liquid–liquid extraction. Switching the position of flasks A and B allows extraction with a heavier-than-water extraction solvent.

Note
A typical apparatus for simultaneous steam distillation-solvent extraction with a lighter-than-water extraction solvent is shown in the figure below.
